Utva 66


Dipl.-Ing. Branislav Nikolic and Dipl.-Ing. Dragoslav Petkovic working for the Fabrika Aviana UTVA at Pancevo, Yugoslavia designed an aircraft intended for the agricultural role, but with many secondary roles. The Utva 56, registered YU-BAF, flew for the first time on April 22, 1959 powered by a 260 hp Lycoming GO-435-C2B2.

For series-production the sole prototype was developed into the Utva 60, mainly differing in having a 270 hp Lycoming GO-480 engine. During development the multi-purpose utility role became the prime target. Small cargo or two stretchers could be loaded through the upward-hinged rear cabin window. The floatplane prototype flew 29 October 1961 equipped with Edo floats, production types were fitted with BIN-1600 floats designed by Nikolic.

Early 1967 a refined version of the Utva–60 appeared, having a Lycoming GSO-480 engine. The Utva 66 had among other changes: fixed leading edge slots, larger tail surfaces, increased fuel capacity and like its predecessor it could be fitted with floats. The aircraft was used by civil and military operators in many roles, like training, medivac, searche and rescue, glider-towing, aerial photography, and agricultural.

Over 130 of the Utva 66 were build, including 117 for the Yugoslav AF:

    4 prototypes, s/n 51001 to 51004
    108 production, s/n 51101 to 51185, 51201 to 51222, 51247, 52101 to 52105.

After service with the Yugoslav AF a large number came on the civil registry, between 1999 and 2001 at least 20 came on the registries of Canada an the USA.
